Resin composition and method of producing laminate

Abstract

Provided is a resin composition for forming a resin layer of a laminate by coating, the resin composition having a thixotropic index at 25° C. of from 3 to 10, and the laminate includes a pair of members and the resin layer arranged between the pair of members.

What is claimed is: 
     
       1. A resin composition for forming a resin layer of a laminate by coating, the resin composition having a thixotropic index at 25° C. of from 3 to 10 and having a viscosity of from 0.6 Pa·s to 3.5 Pa·s at 25° C. and 5 min −1  (rpm), and the laminate comprising a pair of members and the resin layer arranged between the pair of members,
 the thixotropic index being a ratio (viscosity B/viscosity A) of a viscosity B (Pa·s) measured under conditions of 25° C. and 0.5 min −1  (rpm) using an E-type viscometer with respect to a viscosity A (Pa·s) measured under conditions of 25° C. and 5 min −1  (rpm) using an E-type viscometer. 
 
     
     
       2. The resin composition according to  claim 1 , comprising an epoxy resin. 
     
     
       3. The resin composition according to  claim 1 , comprising:
 an epoxy monomer having a mesogenic skeleton; and 
 a curing agent. 
 
     
     
       4. The resin composition according to  claim 3 , wherein the epoxy monomer having a mesogenic skeleton comprises a compound represented by the following Formula (I): 
       
         
           
           
               
               
           
         
         wherein, in Formula (I), each of R 1  to R 4  independently represents a hydrogen atom or an alkyl group having from 1 to 3 carbon atoms. 
       
     
     
       5. The resin composition according to  claim 3 , wherein the curing agent comprises a phenol novolac resin. 
     
     
       6. A method of producing a laminate, the method comprising:
 forming a resin layer using the resin composition according to  claim 1  on a first member; and 
 arranging a second member on the resin layer. 
 
     
     
       7. The method according to  claim 6 , wherein the resin composition comprises an epoxy resin. 
     
     
       8. The method according to  claim 6 , wherein the resin composition comprises:
 an epoxy monomer having a mesogenic skeleton; and 
 a curing agent. 
 
     
     
       9. The method according to  claim 8 , wherein the epoxy monomer having a mesogenic skeleton comprises a compound represented by the following Formula (I): 
       
         
           
           
               
               
           
         
         wherein, in Formula (I), each of R 1  to R 4  independently represents a hydrogen atom or an alkyl group having from 1 to 3 carbon atoms. 
       
     
     
       10. The method according to  claim 8 , wherein the curing agent comprises a phenol novolac resin.
